This invention relates to improvements in m'achines for manufacturingegg pulp, and in particular it relates to a machine of the suction-koperated type.

In machines for manufacturing egg 'pulp al The object of this inventiontherefore is to provide a machine which will have the necessary lowcontamination factor and will at the same time be rapid in action andsimple in construction. f

To attain the objects I have found for instancel that the needle throughwhich the content of the eggs is withdrawn should besuch that it willquickly and eiectively withdrawn the content of the egg, means should beembodied to prevent excessive introduction of shell fragments into thepulp, the pulp should be passed through conduits which are readilycleanable and should be isolated from the atmosphere to as great anextent as possible to prevent contamination by bacteria present in theair, and the arrangement of the machine should be such that over-fillingof same with egg pulp is prevented.

The machine the subject of this invention thereforeembodies featureswhich will attain thev Fig. 3 is a section of the shell trap andemulsiiler` but'with the several members partly disengaged from eachother,

Fig. 4 is an enlarged View of the needle,

Fig. 5 is a side elevation of the head of the machine, l n

Fig. 6 is a fragmentary sectional view but showing the movable part ofthe head in its lowered position,

Fig. '7 is an enlarged sectional view on line 'I of Fig. 5, while Fig. 8is a section as on line 8 of Fig. 7.

The needle I is supported to depend from a suction line 2 and has itslower end closed by a sloping floor' 3. Immediately above the lowermostedge of this downwardly slopingfloor 3 is an aperture 4 whichcommunicates with the inside of the needle. The needle is held to thesuction line 2 by a screwed nut 5 'which engages upon a dependingthreaded portion of the suction line and which bears against a shoulder6 upon the needle. In this way the needle can be rapidly removed forcleaning or replacement. To ensure a goodr joint between the needleandthe suction line the shoulder 6 has a tapered top 9. To pre- 5 ventdraining of the suction1ine2 throughthe needle when suction is cut offthe needleis preferably made of` such length that its top projectsslightly abovethe oor of the suctionV line as shown in Fig. 2 of thedrawings; 10C?. The egg shell trap comprises a vessel II having withinit a removable cylindrical screen I2 v which is coaxially disposed insuch vessel and is located therein to leave an annular space between itand the vessel. The screen I2 terminates some -fdistanc'e above thefloor of the Vessel and has Coaxially disposed within this screen I2 isatube `-""terminates immediately above the lloor of the vessel II so thatwhen suction is'applied to the tube it will draw the egg pulp out of thevessel.

The vessel II, screen I2 and tube I5 are all detachably supported upon ahead' Il 'which has through it a central bore down which the .tube

I5 projects and is provided with an expanded portion 1ine'2 intocommunication with the inside of the screen I2. The head I 'I has alower inter- T-nally threaded llange I9 into'which a flange 20 upon thetop of the s-creen I2 is adaptedto be located, a threaded portion 2|upon thetop of the vessel II being arranged to engage thethreaded'flange I9 and hold the ange 20 of the V-f'P-cie'eri I2 inplace, the several contacting faces being of a sufficiently goot t toprevent `air'leakage. VThe tube I5 has near its top aseries ofemuls'ifying apertures 22 which communicate with an expanded portion 23of the bore of the head 495W, this expanded portion communicating with acontinuation 24 of the suction line 2.

By means of the just described arrangement when suction is placed uponthe line 24 such suc- I tion isvcommunicated to the inside of the tubeTD5 through the emulsifying apertures 22 and thence through its lowerend to thevessel' II. This suction causes a ilow intoand through theneedle and along the suction line 2, through thel and being drawnthrough the tube I5 to the sucr ntion line extension 24. The tube I5 isheld in m place by having upon its `top alvilange 25 which acrossit afloor I3 having a central aperture I4.y

tion I8 the purpose of which is to place th'e suceffected by m-eans of atapered portion 34 on the stem 3|.

The suction line 2 and extension 24 are pro-` vided with caps 35 and 35respectively to facilitate cleaning.

The container 30 depends from an upper bracke f1 et 38 to which it isheld by having a tubular ex-` tension 39 engaging in a socket 40 uponthe bracket 38, the socket being provided lwith :a1

clamping screw 4l whereby the extension-may be locked in position. Thesocket 40 has withiniit' a chamber 42 which communicates with a flexibleair lline143.

The lf'container-il fis held to the 'top.29 by means of ar centralfrodr45 which is secured to.

the bottom of th'e containerI 39 by a-ltapered-por,

tion 46 and a lock-nut 41, the rod having-its top projectingfthrough thesocket 148 uponthe -brackx 1 et 38-v and engaged by ahand\wheel 48whichhasv w a threaded portion engaging the -thre'adedlitop of the rod.A resilient1packng49 is interposedbetween the rim oi" thef container`3i) and fthe topf 29 to eiec't anairtight seal. Thecontaineris providedwith 4"an outlet tap 50 of any. .usuallor approvedconstruction, .whichtap .is preferably. locatedlsomedistance abovethe floor of the .con-r itainer as shown.- so that the .lowerpartof ther container forms asumpfor any .smallparticles of shell Which-might passthe. shell trap.

The 'Stop of the' containerfis preferably profV vided-witha closable airinlet 5l, thezpurposepf- ,f

which is =to permit :the vacuum in such.' container to be moreeffectively brokeniwhenremoving the:

egg pulp throughv the tap 59. r;

A guardl 52 carried .upon the rod `i5 prevents splashingof the pulp.from the containeriagainst the top 29.

The bracket38 is supported uporr-a: vertical column-.53 toi bemovableiaxiallyl thereon; rows of ballv bearings H5.4 disposedlbetween"Y a. supporting stemztr upon.. the top of the column=53 and a,cylindricalbearing member55 upon the bracket 38 facilitating. suchmovement and ensuring a support.. having ,very low rictional resistance.

The ball bearings 54 are held in cages 51 and engagein vertical groovesin the. cylindrical bear.

The'spring isI enclosedV in a cover 61. Theten sion of the springfellmaybe madeadjustable by interposing -a collarebetweenit and the rest Y95and "supportingthe collaraon setscrews passing through the rest.

Supported by thevstem'ill of the column -53 iss 1 line 1| in which is acontrol valve 12. The valve comprises a gate 13 operated from a shaft 14by a iinger 15, the shaft 14 having upon it a lever 15 upon which is acam 11 having a notch 18.A

The means which control the valve 12 comprise a vertical rod supportedin bearings 8l upon the cylindrical bearing member 55, the rod beingprovided with an adjustable stop 82 and aiv spring 83 arrange-d tonormally project the rodupwards. lWhen the container 30 is empty orcontains egg pulp below the amount `at which it is set to operate thevalve is held open by the end of the-md80 engaging the notch 18 as shownmore particularly in Fig. 5. When however the weight of pulp within thecontainer reaches a predetermined amount .the downward movement of the.bracket 38 causes the stop 82 to contact with the y upper bearing 8lunder influence of the spring 83 whereupon continued downward movementiofthe .bracket `38 withdraws: the endof the rod 89 from the; notch.18and-:permits .thetlever 16 to fallto the .positionf'shown in Fig. .6,this` action shutting off the suction line from'the. cony erating armccupledby means of a'linkI 88 to a stud 89 uponqthebracket'f38pthelink'fhaving a slot 90 to permit some 'amount of downward movementof thebracket138 before' the. counter f is operated,4 .t The column-53 issecured to a base92 which base alsosupports `a:platforn'n93 upon whichratin maybe placed .-when'llingfsame from the.: container. 30.

AIf the pulp does not flo-w out of thecontainer 30 freely enough the airinlet tap 5I is opened to permit a greater iiow of air` into thecontainer to break the partial vacuum therein.

The machine can be readily cleaned after operation by drawing acleansing iiuid through same or by dismantling which as will be seenfromthe drawings can be easily carried out, the needle I being removablefrom the suction line 2 and the screen I2, vessel Il and tube I5 beingall removable from the head I1, the entire needle and egg shell trapsection being removable from the container 30 by disengaging the nut 32.The container itself is removable by unscrewing the hand wheel 48 torelease the rod 45 whereupon the container will be free for removal.
